PCF8574 / PCF8575 I2C IoExpander for Arduino and mbed
IO Abstraction library fully supports the PCF8574 8-bit and PCF8575 16-bit IO expander chips on Arduino and mbed. It requires only two pins (three for interrupt mode) SDA, SCL, and optionally INT. Our driver integrates the interrupt support for you so you can attach interrupts very easily. The PCF8574 provides 8 additional input or output ports, but there are few limitations...
AW9523 I2C IoExpander with LED controller - Arduino and mbed
IO Abstraction library fully supports the AW9523 16-bit IO expander chips on Arduino and mbed. It requires only two pins (three for interrupt mode) SDA, SCL, and optionally INT. Our driver integrates the GPIO, LED controller, and interrupt support providing nearly all functions using familiar Arduino terminology. This device can even be used in conjunction with an AW9523 analog device ...
MCP23017 I2C IoExpander for Arduino and mbed
IO Abstraction library fully supports the MCP23017 16-bit IO expander chips on Arduino and mbed. It requires only two pins (three for interrupt mode) SDA, SCL, and optionally INT. Our driver provides nearly all functionality using similar terminology to Arduino itself. The MCP23017 provides 16 additional input or output ports, they have very similar capabilities to device pins and interrupt support...
MPR121 I2C Touch/IoExpander/LED controller - Arduino and mbed
IO Abstraction library fully supports the MPR121 12-bit Touch control and IO expander chips on Arduino and mbed. It requires only two pins (three for interrupt mode) SDA, SCL, and optionally INT. Our driver integrates the Touch, GPIO, LED controller, and interrupt support providing nearly all functions using familiar Arduino terminology. This device can even be used in conjunction with an...
